Application filed me 26 To allwiwm it may concern.-

effect will be ton thereof and Fig.

a is fixed in vertical Be it known that I, ROBERT M. ZARUoHA,

a citizen of Germany, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Radiators for Motor-Vehicles, a specification.-

The presentinvention relatesto radiators of which the following is for motor vehicles and has for its principal,

object to provide radiator whose cooling greatly enhanced.

Another object of this invention is toprovide a construction in which the water will circulate through individual"independently controlled tubes whereby in case of leakage occurringin any one of the tubes, the defective tubecan be shut off leaving the radiator' intact.

A still further object is todetachablyjoin the water tubes to the tanks or'chambers ofthe radiator in order to facilitate repairs and permit defective tubes to be easily and quicklyreplaced bynew ones.

A; still further object of this invention is to impart a certain resiliency to the radiator inorder to lessen its liability "of cracking or breaking as a result of shocks occurring in case of collision or when the machine runs over bumps. a

With these and other objects in view, my invention substantially consists in the novel construction, combination and arrange ment of parts which will be hereinafter more fully described and defined in the appended claims.

In the accompanying drawing which forms part of this specification and in which similar reference characters denote corresponding parts, Figure lisa front elevation of my new radiator; Fig. 2 is a vertical sec- 3 is an enlarged vertical section on line 3-3 of Fig. 2.

Referring to the drawings more in detail, 10 denotes the cast iron frame of the radiator which may be made of any of the usual shapes and sizes to fit different types and sizes of motor vehicles and which, as usually, position in front of the motor or of the fan (not shown). This frame is formed on top and bottom with water tanks or chambers 11 and 12 respectively while the space 10' tanks is open both in the front and back. The tanks 11, 12 are formed at the rear with Specification of Letters Patent,

tubular projections 11, 12 which by hoses 13, 14 are adapted to be connected to similar tubular projections leading from the cooling mantle of the motor. (Not shown.) The tank 11 is provided with'the usual filling opening 15 adapted to be normally closed by the "stoppers 15'. The two tanks 11, .12 are adapted to communicate with one another and through a systemof tubes 16each preferably made in form of a comparatively closely wound coil... The tubes 16 are arranged parallel to one cally in the open space 10 of the framelO and are connected in sets, sothat each set is adapted to form a unit. To this end'each unit is composed of two vertically superposed tubes, 17, 18 extending horizontally and transversely through the open space 10' of theframe 10, and to which a plurality of the coils 16 are suitably and communicatively fixed. The rear ends of these tubes 17 18 are closed while the front ends thereof are bent to form vertical elbows 17, 18 the extreme endsof which are screw threaded. These elbows extend toward the. respective'tanks 11, 12. From the bottom of the tank 17 and the top of the tank 18 project a pluralityofnozzles 19 to which the elbows 17 18' of the tubes 17, 18 are to be tightly connected by nuts 20 loosely mounted on the nozzles 19 and adapted to screw on the threaded portions of the elbows 17', 18'. The nozzles 19 are fixed in beam shaped enlargements 11 12? extending longitudinally along the lower and upper parts of the front walls of the chambers 11, 12 respectively. These enlargements have each a row of vertical bores 11 12 leading into the nozzles 19 and through which the respective chambers 11, 12 are adapted to communicate with the coils 16. Each of the passages 11 ,712 is controlled by a valve 21, which in the present example, is shown as a one way plug or'cock. The plugs are screw threaded and work in threaded bores 11, 12 extending transversely through the enlargements 11 12 from the front wall of the frame. The front or head faces of said plugs are notched as at 21 for the insertion of a screw driver.

The number of sets of coils 16 used clepends upon the size of the motor vehicle. In the present example ten sets of such coils are shown, each set comprising four parallel coils fixedto the tubes 17, 18 and forming another and vertiand return into the tank 11. The circulation then repeats itself. 7

In order to conceal the joints of the coils and thereby lend the radiator a neat appearance, detachable metal strips 23 are provided which extend over the outer face of the frame along the longitudinal upper and lower edges of the free space thereof. The ends of these strips are countersunk in grooves 10 provided in the side walls of the frame an'd are fixed in position by screws 24. These strips normally cover the upper 'and'lower ends of the coils and are removed only when a unit is to be removed.

In'the tank 11 an angular baffle plate 25 is provided which in its apex has an openin '25.

Vh'at I claim and desire to secure'by Letters Patent is:

1. In a radiator for motor vehicles, a pair of superposedtanks each formed in front with an inwardly projecting rib having a number of independently controllable circulation passages, nozzles projecting outi wardlyfrom said passages, a corresponding number of circulation units, each composed of two superposed horizontal tubes the rear ends of which are closed and the front ends are open and removably joined to said nozzl'es, and a plurality of coils extending between and communicating with each superposed pair of said horizontal tubes.

2. In a radiator for motor vehicles, a pair of superposed tanks each formed in front with an inwardly projecting rib having a number of circulation passages, nozzles projecting outwardly from said passages, a corresponding number of circulation units, each composed of two superposed horizontal tubes the rear ends of which are closed and the front ends are open and removably joined to said nozzles and a plurality of coils extending between and communicating with each superposed pair of said horizontal tubes, and a valve for each of said passages.

In a radiator for motor vehicles, a pair of superposed tanks each formed in front with a number of circulation passages, the mouths of the passages in the upper tank being at an elevation from the bottom of the tank,- nozzles projecting outwardly from said passages, a plurality of circulation units, each composed of two superposed elbow tubes remova'bly fixed to said nozzles and closed at one end and a number of coils communicatingwith each pair of superposed elbow tubes.

In testimony whereof I afiix my signature in presence of two witnesses.
